P0803 code but the Eliminator resistor is good
Hi Guys,
I'll start from the beginning. Always a good place to do that...
I bought my '99 FRC almost 2 years ago and it had a skip shift eliminator already installed. Up until about a week ago it was working perfectly. Then I noticed an occasional difficulty pushing the shifter through the reverse gate. Nothing much. Just a little "stickiness".
Yesterday was different. I parked in the local metal supply to pick up the plate material for my tunnel plate. When I tried to put her in reverse she balked. Completely. The DTC code showed the P0803C and refused to clear. So I waited a few minutes until the parking lot was clear and pushed her backwards. (Nothing as embarrassing as having a bitchy girl-friend throw a temper-tantrum in public ;-))
I got her home and still no reverse.
So I searched the forum and found many references to the resistor burning out in the Eliminator. So I now have her butt up in the air and the Eliminator in my hands.
But the resistor shows conductivity and 16Ω!
Is this possibly a fault in the PCM or could the tranni be low on fluid? There is a bit of a leak and I'll check the level in a few minutes.

The SKIP SHIFT "CAGS" is totally different than the reverse lock out solenoid.
Unless the Lock Out Solenoid is bad (and the solenoids are well known to sieze up), you should be able to PUSH THRU the block gate. It takes a bit of force. (I think its 25 lbs) but, it should be able to still get into reverse.

I see in other threads that concern the reverse lockout that checking fuse #19 is a starting point.
Yeppers. The fuse was blown. #19
Does anyone happen to know what size socket fits the solenoid? My fingers estimate 1-3/8".
Thanks Bill for setting me straight on where to look for the problem
